I relaxed my hair at 13 weeks post relaxer on September 5th, 2013. I used ORS Olive Oil Lye Relaxer in Normal strength. Right after that, I got my ends trimmed (salon) because my ends were thinning. The only thing I could attribute it to was the recent use of the New Scurl No Drip formula (never again). I had a love/hate relationship with this moisturizer. Some days, my hair was moist (to a certain extent) other days my hair was dry as chip! I stuck it out and consistently used it hoping my hair will adjust...lo and behold my ends suffered due to the lack of moisture.
Overall, I have no issues with trimming my hair when necessary as I've already reached my goal of MBL. At this point, I'm just maintaining Mid Back Length. Since the trim, my hair is just below Bra Strap so I have a couple more inches to go until I'm Full MBL again (whenever I do a big trim, I usually go back to BSL then grow it out to MBL and maintain). Right now, I'm all about "babying my ends" and making sure it gets the proper moisture it needs.
